NGUI 3 Support / Re: Help migrating inventory system made with UnityGUI to NGUI

« on: August 10, 2013, 04:05:39 AM »

There's a couple of lines the inventory example that I didn't know what purpose they served...

1. Bounds b = new Bounds();
2. b.Encapsulate(new Vector3(padding * 2f + (x + 1) * spacing, -padding * 2f - (y + 1) * spacing, 0f));
3.  

What do they do, are they related to my problem?

Yes I have looked, I managed to get somewhere... I created an empty scene and managed to instantiate the slots inside a backpack (just like in the example, a slot has a background and an icon) - everything worked well, slots had colliders attached to them, they acted perfectly like buttons, I also attached a collider to the bag and managed to drag it around using UIDragObject (I had to increase the z of the bag collider to detect the buttons/slots clicks)

But the problem is, when I went over to my project and do EXACTLY the same thing, I got the slots drawn but they did NOT detect input ((( they had colliders attached to them, I tried changing the depth, the z I tried everything, buttons did NOT detect input at all ( any idea why?

I have the InventoryManager as a child to my panel.

Here are my scripts:
1- Here's how I add a new bag to the inventory (which is a child to the panel)

1. GameObject bagObject = NGUITools.AddChild(gameObject, bagPrefab);
2. bagObject.transform.parent = _transform;
3.  

2- Here's how I'm adding the slots to the bag:

1. private void PopulateSlots()
2. {
3.         for (int i = 0; i < nRows; i++)
4.         {
5.                 slots.Add(new List<Slot>());
6.                 for (int j = 0; j < nCols; j++)
7.                 {
8.                         GameObject slotObj = NGUITools.AddChild(gameObject, slotTemplate);
9.                         Transform slotTrans = slotObj.transform;
10.                         float x = -bagWidth + SPACE_BETWEEN_SLOTS * (j + 1) + j * slotSize;
11.                         float y = -SPACE_BETWEEN_SLOTS * (i + 1) - i * slotSize - headerPadding;
12.                         slotTrans.localPosition = new Vector3(x, y, 0f);
13.  
14.                         try
15.                         {
16.                                 var slot = slotObj.GetComponent<Slot>();
17.                                 slot.Init(new Index2D(i, j), slotSize);
18.                                 slots[i].Add(slot);
19.                         }
20.                         catch (Exception e)
21.                         {
22.                                 Debug.Log(e.Message);
23.                         }
24.                         availableIndices.Add(i, j);
25.                 }
26.         }
27. }
28.  

This is the Start of the Bag, where I call the previous method, and set the collider right for the bag:

1. private void Start()
2. {
3.         bagHeight = nRows * (slotSize) + HEADER_SPACE + (nRows+1) * SPACE_BETWEEN_SLOTS;
4.         bagWidth = nCols * (slotSize) + (nCols+1) * SPACE_BETWEEN_SLOTS;
5.         _collider.size = new Vector3(bagWidth, bagHeight, 1);
6.         _collider.center = new Vector3(_transform.localPosition.x - bagWidth / 2, _transform.localPosition.y - bagHeight / 2, _collider.center.z);
7.         background.transform.localScale = new Vector3(bagWidth, bagHeight, 0);
8.         PopulateSlots();
9. }
10.  

Here's how I'm setting the colliders for the slots:

1. void Awake()
2. {
3.         _collider = GetComponent<BoxCollider>();
4.         background.transform.localScale = new Vector3(size, size, 1);
5.         icon = null;
6.         _collider.size = new Vector3(size, size, 1);
7.         _collider.center = new Vector3(size / 2, -size / 2, _collider.center.z);
8. }
9.  

Any idea what's going on? what am I missing? I'm going nuts, I'd REALLY appreciate any help. Thanks.

NGUI 3 Support / Help migrating inventory system made with UnityGUI to NGUI [SOLVED]

« on: August 08, 2013, 10:56:18 PM »

Hello, I'm completely new to NGUI, I have watched the tutorials, videos and whatnot but I'm still lacking skills.

I have an advanced inventory system that I've been working on for the past 2 months or so here's an old demo http://www.youtube.com/watch?v=J-RxdtzI6Hs

My understanding is that I should first create the buttons/slots and then instantiate them somehow.
But there's a lot of things that I don't know how to achieve, for example in UnityGUI I could provide by buttons with an image, they would show the image but still maintain the button's background. how can I do that in NGUI? I messed around with 'image button' template but didn't seem to know how to make an image appear on it :/

The way I'm drawing my bag (inventory) is that i have a loop looping over my slots and doing:

1. var rect = new Rect(slots[i][j].position.x, slots[i][j].position.y, slots[i][j].width, slots[i][j].height);
2. var button = GUI.Button(rect, slots[i][j].texture, slotStyle);
3. if (button && !contextMenu.shouldBeShown && acceptInput)
4. // do stuff...
5.  

How can I convert that code to NGUI?? :/

If you notice from my video, whenever I pickup an item, there's a box drawn around it (using GUI.Box). As well as a custom cursor texture and the item texture (using GUI.DrawTexture)... how can I do those things in NGUI?? :/

(If there is any important stuff that I should be aware of, please let me know if it)

Thanks a lot in advance...
